Answer:
The correct choice would be greater than or equal to 82
Step-by-step explanation:
If tickets are sold for 4 dollars and 82 tickets are sold than you have 328 dollars 328 plus the 72 from the bake sale is 400 equal you also must take into account that more people might buy tickets but the bare minimum would be 82 so greater than or equal to is the correct choice
Answer: Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. ... If an integer is greater than zero, we say that its sign is positive. If an integer is less than zero, we say that its sign is negative
so 8 9 10 is positive and -8 -9 -10 is negative
they cancel each other out like 8+-8 = 0 and -8+4=-4

For this case we have a system of two equations with two variables given by "x" and "y" respectively. We must solve the system by finding the values of the variables. For this, we follow the steps below:
Step 1:
We multiply the second equation by 3:
Step 2:
We add both equations:
Step 3:
We substitute
in the first equation:
Thus, the solution of the system is given by 
Answer:
The second equation must be multiplied by "3" to eliminate the terms of the "x" when added with the first equation
The first equation must be multiplied by "2" to eliminate the terms of the "y" when added with the second equation
The system solution is given by
